Definitions
- the invention relates to a method for simple separation of the colored components of a fermentation solution during purification of microbially produced compounds that are in solution in the Fermentation solution.
- Microbial fermentation processes have become on an industrial scale has been tried and tested for many years because it makes it relatively easy Sort of has access to larger amounts of substances by means of chemical synthesis not, only with difficulty or only in small quantities are accessible.
- the compounds produced by means of microbial fermentation are in the Fermentation medium usually in dissolved form and must be This is isolated and cleaned. On a laboratory and research scale this is usually not a major problem since it is sufficient standard chromatographic methods are known, impurities cut off. On the technical scale, however, one is on simple, quick and inexpensive procedures instruct the desired product without further, major losses in yield in purified form isolate, if possible without the general continuous To disturb process process significantly.
- the fermentation medium is usually colored.
- the coloring partly stems from the fermentative components of the cultivation medium yourself, on the other hand it can also be opened (unwanted) formed intermediates, metabolites or aggregates of Return end product. In most cases, the coloring can not included together by separating the coarser components the cells and cell debris of the microorganism from the medium completed fermentation.
- Activated carbon is mostly used today to remove unwanted color to remove.
- the color-bearing fabrics are usually on the Activated carbon adsorbed.
- this method is only suitable if the desired product is not also adsorbed.
- the use of activated carbon leads to more or less significant losses in yield.
- the activated carbon is mostly in slurried form must be supplied and usually after adsorption must be washed out several times in order to reduce the yield losses to minimize. This usually has an undesirable effect Dilution effect.
- the US 4,758,347 describes a method for cleaning / decolorization of dye-containing Waste water in a pretreatment stage by adding acid or alkali to a pH in the range of 4 to 9 are set using a two-stage Membrane separation process.
- WO 91/04342 discloses a process for producing a mixture of fructose, glucose and compounds of the general formula GF n , where G is glucose, F is fructose and n is an integer, the mixture consisting of the tubers of Jerusalem artichoke or of roots the chicory is obtained by a process which does not involve any chemical modification of the components of the mixture.
- the membranes must have a separation limit of 150 to have a maximum of 500 u (150-500 daltons), that is, substances with a molecular weight from well below the separation limit are able to the membrane area to permeate, whereas substances with a molecular weight retained above the separation limit (nanofiltration).
- the Nanofiltration can, as with the known use of activated carbon also, precede a filtration step that causes the coarse Components in the medium are removed from it beforehand (microfiltration).
- the present invention accordingly relates to a method for Purification of low molecular weight produced by microorganisms Compounds in colored fermentation solutions, characterized in that is that the clear colored, freed from coarse constituents Fermentation broth containing the microbially produced products dissolved form contains, through a membrane with a separation limit of 150 to 500 u (150-500 daltons), especially 200 to 300 u (200-300 daltons), filtered and the Compounds isolated from the undyed eluate.
- the subject of the invention is a corresponding one Process, which is characterized in that nanofiltration membranes with a cut-off of about 200 u (200 daltons) for purification of microbially produced compounds with a molecular weight of less than 100 u (100 daltons).
- the invention is a corresponding method for Purification of microbially produced dihydroxyacetone.
- separation membranes required for these purposes with the mentioned Properties are state of the art and commercially available. Separating membranes with a cut-off of about 150 to 500 u (150-500 daltons), the partly unknown yellow and brown dissolved components an otherwise clear fermentation solution almost quantitatively withhold while synthetic products with a molecular weight from well below the respective separation limit in good yields permeate through the membrane.
- more yield based on the crystallization step in Connection to the filtration or the coal adsorption
- nanofiltration step according to the invention can be achieved in comparison for cleaning with activated carbon under otherwise the same initial and Aftercare.
- the appropriate substances should preferably have no or only small charges, since hydration shells become one lead to greater effective molecular weight.
- connections like Dihydroxyacetone, sorbose (ascorbic acid production), or also biotin there are also fermentatively produced amino acids and peptides nearby their isolelectric point by means of the membranes mentioned colored components separable.
- Another advantage of the method according to the invention is that in addition to the increased yield the product resulting from the fermentation solution can crystallize out after nanofiltration, a better one Has more quality than the treatment with activated carbon. So are for example, the so-called yellow values, which differ from solutions let crystallized product (2nd crystallization) be determined, clearly lower than with the coal adsorption method.
- Nanofiltration is suitable for all common technical fermentation processes, regardless of which microorganisms and which Media compositions are available. Ultimately, the decisive factor is effective size of the product formed. The further the size of the Product is below the exclusion limit, with the higher Yields of a particularly pure compound can be expected.
- the nanofiltration can also be carried out without an upstream microfiltration be so that a purification step can be saved.
- the process is particularly beneficial for the purification of microbial prepared dihydroxyacetone suitable. But also for example with the Process for the microbial production of sorbose (ascorbic acid extraction) good results can be achieved.
- the solution was sterilized (20 min, 120 ° C) and after cooling with Inoculated 5 - 10 l of a densely overgrown pre-culture of the bacterium.
- the fermenter was allowed to grow the bacterial culture for about a day and implement. The duration was based either on the measured Residual amount of glycerin or after oxygen uptake, measured according to Standard methods. The reaction was stopped as no glycerin there was more in the approach.
- the fermentation broth obtained according to Example 1 is by microfiltration (Pore size 0.2 ⁇ m) according to standard methods of solids free of any kind.
- the clear filtrate was then fed to a nanofiltration system: Release material Dow NF 45, separation limit 200 u (200 Da), Membrane area 50 sqm (winding modules), print 20 bar, Permeate flow with filtrate from Example 1 7 l / sqm h.
- the fermenter solution was filtered on the membrane surface.
- the coloring components were retained while Water and the product permeated the membrane.
- the clear, undyed DHA solution was evaporated to the viscosity.
- the product was crystallized from concentrate with cooling from acetone. Yield 76% white crystals. Some crystals were dissolved in water (25% solution) and the yellowing as a measure for those still present Impurities measured (according to Hazen A., 1892, Am. Chem. J. 14, 300). A relative yellowness index of 4.6 was determined.
- the pH of the Solution was 5.6.
- the fermentation broth obtained according to Example 1 became as in Example 2 described, first subjected to microfiltration.
- L-Sorbose was produced by fermentation using Acetobacter suboxydans using standard methods. The fermentation broth was treated and cleaned as in Example 2. A membrane material with a separation limit of approx. 300 u (300 Da) was used for nanofiltration. High-quality crystals of L-sorbose (yellow value: 5.0) were obtained in good yield.
